Concept Relations
Concept relations
Concepts are the recurring ideas that appear across your notes — the vocabulary of your thinking. Just as notes can be typed, so can the connections between concepts.
Concept relations are simpler than note relations. There are only four, and they describe the structure of your vocabulary itself — which ideas contain others, which repel each other, which travel together.
Concept relations build your personal ontology. Over time, they reveal how your mind organises knowledge — which concepts are central, which are peripheral, where the real tensions live.
The four types
Broader
The linked concept is a wider category that contains this one.
"Cognitive load" is broader than "working memory load".
Narrower
The linked concept is a more specific instance of this one.
"Decision fatigue" is narrower than "cognitive load".
Related
The two concepts are connected but neither contains the other. They tend to appear together.
"Attention" and "flow state" are related — each one often pulls in the other.
Opposite
The two concepts are in direct tension or polarity.
"Slow thinking" is opposite to "fast thinking" in the Kahneman framework.
Why it matters
When Relinkia surfaces a connection suggestion, it considers not just which notes share concepts — but how those concepts relate. A note about “slow thinking” and a note about “fast thinking” are more interesting together because the concepts are opposite, not just related.
You don't have to map every concept relation. Start with the ones that feel important — the concepts that sit at the centre of how you think about a subject.
